abstract = "The nanocomposite of diamond deposited on carbon nanotubes (CNTs)
emerged as an alternative to get Boron-Doped Diamond (BDD-CNTs)
and Nitrogen-Doped Diamond (NDD-CNTs) porous films. This work got
excellent wet individual seeding of each carbon nanotube of a CNT
forest with minimum changes to its original morphology. The use of
an oxygen plasma to graft polar groups on the CNT surface enabled
efficient electrostatic self-assembling (ESA) of nanodiamonds from
a dispersion in a KCl diluted solution. The use of other routes
with polymer functionalization and/or polymer based nanodiamond
dispersion always left some residues and promoted nanodiamond
bridging among carbon nanotubes. Even though any of the
alternatives may produce porous diamond-CNT composites, the one
grown to reproduce closely CNT morphology may allow much better
results, as a larger surface area. Thermal Chemical Vapor
Deposition (CVD) via floating catalyst produced the CNTs. Two
different procedures promoted functionalization, either by
immersion in the cationic polymer PDDA (Poly
Diallyldimethylammonium Chloride) or O2 plasma functionalization.
Seeding went on from 4 nm diamond particles dispersed either in DI
water with the anionic polymer Poly Sodium Styrenesulfonate (PSS),
or with a KCl solution in DI water. A Hot Filament Chemical Vapor
reactor deposited diamond film on the CNTs. The composites were
characterized through Raman Spectroscopy, Scanning Electron
Microscopy with a Field Emission Gun (FEG-SEM) and Energy
Dispersive X-ray Spectroscopy (EDS).",
